To all when it may concern: Be it known thatwe, ERASIL'S E. WIXKLEY and Fnnn V. IIART, citizens of the ['nited States, residing at Lynn,.in thecounty oi Esscx'and State of Massachusetts. have invented certain new and useful Improvements in Hydrocarbon- Motors; and we do hereby'decla 'e the following to be a full, clear, and exact description oi the invention, such as ,will enable others skilled same. V I

The present invention relates to hydro-carbon mot'orsand more'particularly to that class 'of motors which reversedirection, the time's of operation of the ignition device and of the valves being properly shiftedthereior'.

In the present invention the same method of reversing the motor is employed as in our pending application, and one of the objects of the present invention is to simplify the construction of the controlling devices, so thatthe operator by a single movement of one-hand |nay reverse the motor at will.

A further object is to simplify the construction and improve the operation of other portions of the mechanism so that thepossibility 'of derangement of the parts and failure of the motor to reverse shall be reduced to a minimum.

With these and other objects in view apparent to those skilled in the art, our present invention consists of the devices and combinations of devices hereinafter described and claimed.

1n the accompanying drawings which illustrate a preferred form" of our invention, Figure l is a front elecarried thereby on line zz Fig. A. Fig. 7 is 'a front elevation; of thclev'er; Fig. 8 is a Iront elevation of the v in the art to which it appertains to make and use the- 10 .stroke.- The'inipulsegiven to the piston bythe expandcharge during this expansion strokeof the piston, thus sliding member carried by said lever; Fig. 9 is a top plan view of the actuating mechanism for the ignition.

device and the exhaust valve with the cams and cam shait removed; Fig. 10 is an enlarged view on line a'a, Fig. '9, looking toward the right, showing the actuating mechanism -for the ignition device; and Fig. 1] is an enlarged view on line b-b, Fig. 9, looking toward the right, showing the actuating mechanism. for the exhaust'valve.

The cylifider, the piston -ar,ranged to reciprocate.

therein, the shaft, the suction-operated inlet valve, the ignition device, and the exhaust valve in our improved hydro-carbon motor are-all of the usual or ordinary type. The actuating mechanism for the ignition device and exhaust valve, however, differs from that or; dinarily employed on these motors, and comprises briefly two sets of cams for actuating. the ignition de vice and exhaust valve, one set timed for for'wmd rota tion andthe other set for reverse rotation oi the' motor, a spring-actuated shipping device for throwing one set out of and the other into operation, adetent for preventing the shipping device from operating, means ior rendering the ignition device inoperative, and mechanism operating upon a reversal in the directionof 'ro-' tation of the motor to actuate the detent and to actuate and render operative-the ignition device.

As shown in Fig. 1 our motor comprises the cylinder 1 in which reciprocates the piston 2 which imparts motion' to the shaft 3 through the connecting rod 4 and crank 5. The explosive.mi'xtnre enters the cylinder froin a suitable carbureter or othcrdevice (not shown) through the inlet port 6 having the suction-operated inlet valve 7, and after compression is ignited by an electric spark, the ignition device being of the ordinary make-and-break type having the fixed electrode 8 and movable electrode 9 mounted in the base or support 10 secured to the wall of the cylinder. The fixed electrode is electrically insulated from the support 10 and is connected with one pole of a battery (not shown) or other suitable source of electricity by means of the wire 11; The other wire 12 of the circuit is connected to the threaded pin 13 which is secured in the support 10 and .projects throughjthe coverplate 14. Themovable electrode is actuated by meansoi anarm 141.rigidly' connected therewith and from which projects the pin 142. One arm 15 of a bell crank lever mounted upon' the stud 16 projecting from the support IOengages one side of the pin 142 to actuate thearm 141 to swing the movable electrode 9 out of contact with the fixed elec .tmde 8 to cause a spark withinthe cylinder, ,2; spring 17;

abutment 24 in the head of the cylinder and at the other the top'of the cap 25 provided with the projections 26 extending from opposite sides near the bottom. The nuts 27 permit the position of the projections 26 to be properly adjusted. The valve stem is depressed and the valve opened by means of the lever 28' pivoted at 29 and having the bifurcated or forked end 30 which straddles the cap and engages the projections 26 there on. The -opposite end of the lever 28 is by means of the rod 31 which is actuated by mechanism "hereinafter to be described.

. .As shown in Fig. 2 the main shaft 3 or the motor is .rnounted in suitable bearings 32 and, as is thepractice with hydro-carbommotors, is provided with a fly wheel jahown) operated byan eccentric tric strap 34 and rod 35. p i

The mechanism for actuating the ignition device and (not shown) which is securely keyed npon'the tapered portion 33 of the shaft. The cylinder is water-jacketed and circulation is maintained by means of a pump (not (not shown) and eccenthe exhaust valve comprisw brieflya cam shaft driven from the main shaft of the motor and provided with two sets of cams, one for forward rotation and the other for reverse rotation, and cainlevers actuatedby one or the other of the cams and in turn actuating the vertically.

reciprocating rods 19 and 31 to actt- =te the ignition de vice and exhaust valve, the cam levers being movable lsterallyto be brought into position to be g g d by one or the other of the cams Recording to the direction of rotation of the motor.

As shown on the drawings the cam shaft 36 is driven by gear 37 from gear 38 upon the main shaft and the intermediate gears 39 and 40, gear 39 being twice the diameter of gear 38 so that the cam shaft 36 rotates at hal-fthe speed of the shaft as is the practice with fourcycle motors. Secured upon the cam shaft by the pin 41 is a camniember 42 the cam disks 43 and 44. Upon the cam disk 43 are the cams 45 and 46 foract'uating the ignition device during forward and reverse rotation respectively, what we call forward ro- 'tation of the motor being that indicated by the arrow in Fig. 1. Upon the cam disk 44 are formed the cams 47 and 48 for actuating the exhaust valve during forward and reverse rotation respectively.

Pivotally mounted upon the eccentric 49 secured upon the shaft 50 by mans'of the taper pin 51 is the cam lever 52 having a bifurcated end in which the block 53 is pivoted. A finger 54 depending from the block engages the periphery of the cam disk 43 and is actuated by one or the other of cams 45 and 46. The

block is normally held from turning upon its pivotal support and in the position shown in Fig. 10 by means of the bolt 55 guided in the cylindrical recess 56 in the cam lever 5%,the head 5? of which bolt is pressed against the block by means of the coiled spring 58."

If by any chance the cam disk should he so rotated that the abrupt face of either cam is brought against the finger 54, the blockwill turn upon its pivot, forcing the bolt farther intothe recess against the tension of spring 58 and saving the parts from injury.

The eccentric 49 is formed with a cylindrical portion 60 upon which is pivoted-the lever 61 provided with the horizontal 'part 62 and the vertical portion 63 depending therefrom and having the beveled end 64 arranged to be engaged by the abutment or projection 65 upon the cam lever 52. The top of the horizontal portion 62 engages the bottom of the rod 19 for actuating the ignition device and raises the same as cam 45 or 46 passes beneath the finger 54.

Pivotally mounted upon the shaft 50 is the cam lever 66 having a forked or bifurcated end in which is pivoted the cam roll 67 arranged to be engaged by-one or the other of cams 47 and 48. A projection 68 on this lever engages the bottom of rod 31 and raises the same to open the exhaust valve at the proper time in the cycle of operation of the motor. All three levers 52,

61 and 6Q are confined between the flange 70 on the eccentric 49 and the collar 71 pinned upon the shaft 5050 that longitudinal movement of the shaft in its bearings 72 and 73 will ship all three levers, shifting the cam levers from one set of cams to the other, so that the times of operation of the ignition device and of the exhaust valve shall be shifted for rotation in the opposite direction, the rod engaging portions 62 and 68 being sufficiently long to permit this movement .without their being carried out of engagement with the ends of their respective rods.

The object of mounting the cam lever 52 upon the eccentric 49 instead of concentrically with the shaft 50 as is cam lever 66 is to permit the time of ignition to be varied so that either. early or lateignition may be obtained at the will of the operator. This is accomplished by means of the adjusting handle 75 pinned upon the end of shaft 50 by means of which the shaft may be turned and the eccentric adjusted to move lever 52v longitudinally, causing finger 54 to drop off the abrupt face of the cam at an earlier or later point in the rotation of the cam shaft. The beveled face 64 on the depending arm 63 of lever 6l.is of sufficient length to per mil; this longitudinal adjustment of lever 52 without throwing said beveled face out of engagement with the projection 65 on lever 52. Locking devices are provided so that the lever 75 may be securely held in the desired position and these devices comprise a pin 76 longitudinally movable in a recess in the lever and pressed outwardly by the spring 77. The end of the pin is conical and is arranged to enter correspondinglyshaped recesses 78 in the plate 79 formed integral with the shipping member 80 hereinafter to be described. The plate and member are loose upon the shaft 50, be-

ing confined between the lever 75 and a collar 81 se cured upon the shaft, and they are held from rotation by the arm 82 projecting from the plate and having a forked end which loosely engages the shaft 83.

The shipping member 80 isprovided with two abutinents or projections 831 between which is located the depending arm 832 of the shipping lever 84 pivoted upon the-stud 84l'sec-ured in the depending block-85 upon the reversing lever $6. The reversing lever is provided with a hub 87 pivotedupon the-hollow stud 88 and confined between the collar 89 pinr .1 upon ;94 of the block 92 isprovided with an aperture 96 the stud and the support 90 in which-the stud is 'mounted, w pp rt- 'is Provided ",Wi hra base 91 the slideblock 92 having an aperture-into which the;

projection 85 fits, 'the'aperture being somewhat longer than the projection. The block 92 is provided with the downwardly extending projections or abutments 93 and withthe upwardlyturned-end 94 arranged to enter the recess 95 in the reversing lever 86. The end through which extends the rod 97 having the screwtl1l'(3dd0d head 98'and surrounded by the'spring 99 both rod andspring being located within the reven- -i ng 'lever. Thclspring engages at one end thescrew- A 4 and 6. The shipping lever 84 is providedwith arms.

1( )0 arrangedto beengaged by theabutments 93 on .block 92 which tend normally to hold the shipping lever 84 and the reversing-lever 86 in line'es shown iii-Fig. 6. The depending end 832 on lever 84, however,. may be thrown out of line with the reversing .5

lever relative movement of the ends of these levers, by which movementthe sliding block 92 will be moved 'inwardly'compressing the spring 99 which at the first opportunity will expapd, move the block to the right and swing the levers into alinement'sgain,

,By means of a handle 101 the reversing lever 86 may. be upon its pivotal support and may be secured in the desired position by means of a pinch -lever 102 pivo'te d between the ears 103 rising the reversing flew; and arranged tolatdh home or the dther oi two notches 104 in th'epiece 105'. a ringsoe normally holds the lever 102 raised, ahandgrip107 being vided'in close proximity tothe handlelOl of the shipping lever so that with one hand the operator may depress the pinch leverand then actuate the reversing lever In order to prevent the shait from being shippedimmediately upon the actuatio i of the reversing lever 86', a detent has been provided which is'released at the: proper instant by automatic mechanism. This detent comprises the lever 10$.secure'd upon the shaft 83 'and is provided withtwoprojections 109, one or the other of which may be swunginto a position to engage the arm 110 projecting from theshipping mem ber 80 to prevent movement of the latter when the reversing lever 86 is actuated.

The means 'for' operating'the detent lever 108 to release th'e'shipping member consist of a. bell crank lever pivoted upon a stud 111 projecting from thesup- .port 90 which carrie'sthehollow stud upon which the reversing lever is pivoted. "One arm 112 this bell crank lever'is provided with a head 113 located between projections 114 upon the end of the detent lever I 108., so that said level may be actuated in either difiendish 11% the which issrrsnged to be engaged bythe friction ring or band l17. The stud {118. passing through the endsof the band, the spring 119, thadjusting nut 129Jand check nut 121 act to pinch the ends of the band together to make it grip the disk. In order to spread theends apart so that the band may be loosefupon the disk, 0. pin or rod 122 is provided, the conical end 123 0i which is arranged to enter between the ends of the band andtowedge them apart. This pin passes through the hollow stud 88 and the end of thepinchlever 102 and is raised by the latter by means of the adjusting'nut124 and check nut 125. A spring 126 'withinthe hollow stud'forces the pin or rod 122 downwardly with sufficient force 'to separate theends of the band to loosen the same upon the disk. -Two pins 127 support the bottom of'the band when the ends are iorcedapart sothat when the parts, are in this position which is their normal position during the operation of the motor the band is 'out of en-. gag'ement with the periphery of thed isk. When the pinchlever l0'2 is actuated and the conical end-123 on rod 122 removed irorn between the ends of 'the band, the latter immediately tightens and tends to turn-with the disk. The lowerfend of the arm'115 of the bell crank, lever is provided -.with branches at rightangles thereto from which project the fingers 128' one upon each side of the ends of the band, so that when this turning occurs the arm' 115 is actuated and one of the projections 199 is swung into position to be engaged by 4 the armlltlon the shipping member as soon as the reversing lever is actuated. 1 .Any considerableextentoi movementof the friction band is prevented by a. stop device whichconsists of the substantially square heads 131 .one'oneach side of the .two ends of the band 117 and connected by the portion 132 located between the ends of the band and rectangu I lnr in crosssection. A tail or projection 133 from the rear head 131 is arranged to engage one or the other of the'stop pins 134 according to the direction in. which. the shaft is rotating, not only arresting the movement of .the band but also releasing to a great extent the pressure offthe band upon the disk, as the portion 132' will be turned slightly by the pressure brought upon the pro jection 133 forcing the endsof the band apart. I

The mechanism for rendering the ignition device inoperative consists of two stops or cams 136 secured upon shaft 84 and arranged to be swung one or the other heneath the bottom of the horizontal portion 620i lever 61 when the latter has been raised by cam lever 52- preventing the former and rod 19 from being depressed by spring 20 when the finger 54 drops off the abrupt face of cam 45 and thus holding the electrodes in contact and rendering the ignition device inoperative. Inasmuch as the or stops 136 can be swung under the horizons tal portion 620i lever 61 only when the latter has been raised, the detent lever 108 can be turned to bring one or the other of projections 109 into position to engage arm 110 on the shipping member only at this time-andthe bell crank lever and friction band 117 will be correspondingly limitedas to'their time of operation.

The operation of ourimprovedniotor is-as i0llows: Assuming the motor to be in operation inthe forward direction withthe parts in-the positions shown in the a drawings, the operator when he wishes to reverse the motor first grasps the handles 191 and'lO'Z in one hand,

and depresses ass pinchlever to assess a, which movement raises rod 122-and causes the band 117 to. engagethe friction disk. The bandimmediately'tendstoturn with the disk but will be prevented from doing so to the right Fig. 1 and the left hand cam o'r tion to engage the arm 110 on shipping member 80.

, inoperative, the explosions cease and the speed of the the compression stroke when the high part of cam 45 is 1 length, and leverfil will'be held raised by the cam of shaft 50 and the withdrawal of cam 136 occur so causes the actuation of the ignition device to produce 'and the exhaust valve by cam 48. .The motor may be reversed again boron in forward direction by depressing the upper projection 109 will be swung in iront'of the 5 5 lnd'er, a' piston, a-shatt, an ignition device, means tor shifting the time of operation ofthe ignition devlce tor re-'- verse rorarrdnfar fhTzidfof, aspringiror actuating said means, .a detent, andmeans tor actuating thedetent upon.

see,

'until lever 61 is raised by cam when the band turns a slight distance, actuating the bell crank lever and detent lever l08 which renders the ignition device inop erative' and carries the lower projection 109 into posi- Since something less than two complete revolutioim'of. the motor shaft is the most that can ever be required before the lever 61 will be raised so that the dete'nt may be swung intooperative position, a delay of a few seconds after depressing the pinch lever will be sufficient and the reversing lever 86 may then be moved to the right as shown in Fig. 2 and the pinch lever released tosecure it in the reverse position. The ignition device being motor drops quickly and it soon stops on a compression stroke. No sooner does it come to rest, however, than it begins to rotate in the reverse direction under the ox-' pension oi the compressed charge of unexploded gas in the cylinder. The iriction band immediately starts, back with the disk llli, as the band will grip the disk the instant the pressure of the projection 133 upon stop pin 134 isrelieved and the band will turn with the disk until the end 123 oi ro,d 122 drops into the space between the ends, stopping the band and loosening it upon the disk. ,The reverse movement of the band oscillates the bell crank lever to actuate the detentlever 10S, withdrawing the projection 109 from behind the arm 110 and the cam or stop 136 from beneath the hori-' zontal portion 62 of lever 61. The shaft isinstantly shipped and the ignition device actuated to ignite the expanding. charge. In the motor of the drawings the actuation of the ignition device will generally be caused by the finger 54 dropping off the side of the cam 45 when shaft-50 is shipped rather than by the withdrawing of cam 136 from beneath the horizontal portion 62 of lever 61, for the motor will usually stop on the latter part of beneath the finger 54 as this cam is of considerable after stop 136 has been withdrawn Both the shipping nearly simultaneously, however, that it is immaterial so as the operation of the motor is concerned which the first explosion. 'The motor alter this first explosion takes'up its regular cycle of operation in the reverse directioli, the ignition device being actuated by cam 46 the pinch lever 102 and then swinging the reversing lever to the left in Fig. 2.when the friction band will be stop 136 will hold the ignition device inoperative while arm 110 to prevent shipping of the cams until a'rever'sal in the direction of rotation or the motor.
